Mitochondria are responsible for the essential role in the cell survival by regulating the cellular energy, homeostasis, oxidative phosphorylation process, fatty acid oxidation and in the cell death process by regulating apoptosis. However, reactive oxygen species (ROS) is produced by mitochondria that pose oxidative damage to lipids, protein and mitochondrial DNA and additional production of ROS is triggered by this damage. On the other hand, the host cell control the life and death of... Topics: Mitochondria, Mitophagy, Yeast, Autophagy

The Solar system beyond Neptune is believed to house a population of small primordial bodies left over from the planet formation process. The region up to heliocentric distance -50 AU (a.k.a. the Kuiper Belt) may be the source of the observed short-period comets. In this region, the phase space structure near orbital resonances with Neptune is of special interest for the long-term stability of orbits. There is reason to believe that a significant fraction (perhaps most) of the Kuiper Belt... Topics: MAGNESIUM, RESPIRATION, LIVER, MITOCHONDRIA, RATS, HAMSTERS, SENSITIVITY, TEMPERATURE EFFECTS

Over the past 30 years, interest in extraterrestrial intelligence has progressed from philosophical discussion to rigorous scientific endeavors attempting to make contact. Since it is impossible to assess the probability of success and the amount of telescope time needed for detection, Search for Extraterrestrial Intelligence (SETI) Projects are plagued with the problem of attaining the large amounts of time needed on the world's precious few large radio telescopes. To circumvent this problem,... Topics: BIOLOGICAL EVOLUTION, MITOCHONDRIA, PROTEINS, EUKARYOTES, LOCOMOTION, MARINE BIOLOGY,...

The basic knowledge that mitochondrial enzymes are released by freezing-and-thawing muscle tissue was used to develop a fairly simple objective test to distinguish between meat that has been frozen-and-thawed and that which has never been frozen. Previous studies indicate that glutamic-oxalacetic transaminase (GOT) of muscle press juice (MPJ) can be used for this. The test requires the determination of the relative amounts of mitochondrial isozyme (GOT(M)) and sarcoplasmic isozyme (GOT(S)) that...

The relation between the degree of nonpotentiality of photospheric magnetic fields and the occurrence of gamma ray flares is examined. The parameter delta phi (magnetic shear) and the strength of the magnetic field intensity are used as measures of the degree of nonpotentiality, where delta phi is defined as the angular difference between the observed direction of the transverse component of the photospheric field and the direction of the potential field prescribed by the distribution of...

The effect of sulfur mustard (SM, bis-(2-chloroethyl) sulfide) on intracellular free Ca2+ concentration (Ca2+)i was studied in vitro using the clonal mouse neuroblastoma-rat glioma hybrid NG108-15 and primary normal human epidermal keratinocyte (NHEK) cell culture models. SM depletes cellular glutathione (GSH) and thus may inhibit GSH-dependent Ca2+-ATPase (Ca2+ pump), leading to a high (Ca2+) and consequent cellular toxicity. Following 0.3 mM SM exposure, GSH levels decreased 20-34% between... Topics: DTIC Archive, Ray, R., Majerus, B. J., Munavalli, G. S., Petrali, J. P., ARMY MEDICAL RESEARCH INST...
Paul Giem on Molecular Clocks 5-2-2015A recent article argues that molecular clocks are too fast. This contrasts with claims that the Cambrian molecular clocks are too fast. On the other hand, clocks calibrated by real time (as opposed to evolutionary theory) seem to work well. This has implications for, among other things, the age of humans.1. http://www.sciencedaily.com/releases/2014/12/141202103600.htm2. http://onlinelibrary.wiley.com/doi/10.1111/nph.13114/epdf3.

3-MERCAPTOPYRUVATE SULFURTRANSFERASE (3-MPST: E.C. 184.108.40.206) is an enzyme located in the cytosol and mitochondria of cells and is believed be involved in the endogenous detoxification of cyanide (CN) because it is capable of transferring sulfur from 3-mercaptopyruvate (3-MP) to CN, forming thiocyanate (SCN). In addition, 3-MPST activity is present in the erythrocyte and cyanide appears to be converted to SCN primarily in the blood, providing further evidence that 3-MPST may make a significant...
